COMBINED THIMBLE AND FLUE STOP.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed January l0, 1907. Serial No. 351,718,

To all whom it may concern:

Be it known that I, EDWARD E. IIANKEN, a citizen of the United States, residing at Waggoner, in the county of Montgomery and State of Illinois, have invented a new and useful Combined Thimble and Flue-Stop, of which the following is a specification.

This invention relates to combined thimble and flue stops for stove pipes, and has for its object the provision of a simple and inexpensive thimble that Will hold a pipe securely and that is provided with an improved means for closing the flue when the thimble is not in use.

The invention consists of the novel construction, combination and arrangement of parts hereinafter-described, more particularly pointed out in the claims and illustrated in the accompanying drawings forming a part of this specification, in Which- Figure I is a perspective view of the improved thimble. Fig. 2 is a perspective view of the flue stop. Fig. 3 is a longitudinal vertical section of the combined thimble and ue stop.

Referring to the drawing, the thimble is provided with the usual cylindrical portion having the usual flange 2, and is further provided with a longitudinal groove 3 in the inner lower surface of the cylinder A which extends to the rear edge of the thimble but stops short of its front surface, leaving an inwardly-extending rim 4. The inner edge of the flue is provided with two inwardly-extending lugs or stops 5 5 to prevent the stove pipe from being passed beyond the inner edge of the thimble. The outer face of the thimble is provided with a lug or ear 6 projecting adjacent to the flue and parallel to the axis thereof and provided with an aperture 7 The ue stop 8 consists of a circular closing for the flue having a lip 9 upon its inner side adapted to engage the said recess 3 and behind the said rim 4 of the thimble. The face of the flue stop is provided With a laterally-extending flange l0 adapted to be seated against the outer flange 2 of the thimble and provided with an aperture ll to receive the said lug G of the thimble. A pin I2 fits through the aperture in the lug 6 and extends outside of the flue stop to retain it in position in the flue. When the flue closure is removed and a stove pipe is inserted into the flue up to the stops, an aperture is formed in the pipe opposite the aperture in the lug 6 and the stove pipe is then retained in position by means of the said pin l2. The lug 6 and the pin l2 thus lserve the double purpose of retaining either a flue st op or a stove pipe. The said rim 4 prevents rain Water or condensation from the pipe from running through the thimble and also serves as a fastening for the flue stop, as has already been described.

The thimble and closure may be made of cast or of sheet metal and the thimble is secured in place in a chimney by the usual means of cement or mortar and by nails passing through apertures provided therefor in the cylindrical portion of the thimble.

Having thus described the invention, what is claimed have hereto affixed my signature in the presence of two' witnesses.

EDWARD E. HANKEN.
